While converting a stop-action series of images from the HDR-AS30V into a movie, I wanted change all the image files on a USB Flash drive from
dsc00008.jpg, so as to simplify typing their names.
Alas, because the camera’s exFAT filesystem cares not one whit about case, the obvious command doesn’t work:
rename 's/JPG/jpg/' /mnt/part/* /mnt/part/DSC00008.JPG not renamed: /mnt/part/DSC00008.jpg already exists
So you must do each piece in two steps:
rename 's/JPG/jpgx/' /mnt/part/* rename 's/jpgx/jpg/' /mnt/part/* rename 's/DSC/dscx/' /mnt/part/* rename 's/dscx/dsc/' /mnt/part/*
Obvious once you see it, I suppose…
See the comments for a better way:
rename 'y/A-Z/a-z/' *JPG

I don’t actually know the rename command, but ‘y/A-Z/a-z/’ might be the shorter form of that…
Got it in one!
renamecommand uses a Perl expression and that is a swamp I won’t venture into.
Thanks for the tip…
